I come now to the triminer-arrangement:

.Mounted loosely upon the shaft is a sleeve or hub 13, provided on onesidewith' a hen dle l-l, and on the other side with anal-1n or extension15,- The outer extremity of tlns arm carries a sleeve 16, in which issnugly ournaled a shaft l7. It is to this shaft that the trin-i-mer 18is secnredj' This trimmer may be of, anyimprove'd construction,in

the particular instance illustrated, it consists of a solid lmdy-portionhaving a sufii- (-ient number of openings 19 therein (the trimmer shownin F 3 has three openings). In each of these openingsis adjustablysecured (as by screw 19) a trimmer-knife 20, having a cutting edge 21'.The pulley rigidly fastened to the'projet-ting end of shaft; 17, isconnected by a belt 23 to the pulley 2t seeuredto the shaft; 4 betweenthe hub 13 and the inner bearing 3. It will be observed that inviewofthe loose mounting of the hub 13 on the shaft 4, the trimmer-mechanismwill normally assume a vertical position due to gravity, as indicated indotted lines in Fig. 1. In thig way the trimmer normally in an idle orinoperative position, without leastwise interfering-with the properworking of the saw. In case it is desired to use the trimmer,

I it is simply necessary to grasp the handle 14-.

passed beyond reach of the saw (as .indicated at 24' in Fig. 2), itenters the field of action of the trimmer-knives, which trim it down tothe required size or form. Upon releasing the handle-14, the entiretrimmer-' arrangement drops out of the way, readyto If desired, suitablestops be moved into operative position at any mo- -ment.

' Although I have shown and described one embodiment of my invention,yet I- will have the essence of my invention, as set forth in theannexed claims, is susceptible of other and further embodiments ormodifications -which might suggest-themselves to those skilled in thearand which, therefore, the' appended claims seek to cover;
